Sizing guide



TeraFlex Alpine RT (Rogue Trail) Suspension Systems build on our already capable Alpine CT (Cross-Trail) Suspension Systems. These systems include all our top-of-the-line components. The TeraFlex 6" Alpine RT6 Long Arm Suspension System excels on the highway off-road through the desert or rock crawling! TeraFlex lifts are built on decades of research and development resulting in the ultimate suspension. Includes our HD Drag Link Flip Kit w/ Front Track Bar Drop Bracket & Frame Brace Kit to correct steering geometry eliminate front end shimmy and reinforce the frame. The Alpine RT6 is the pinnacle of JK suspension systems! Adjustable Alpine IR Long Control Arms balance front caster and pinion angles as well as optimize rear pinion angles anti-squat geometry and tire position on vehicles with 3-6" lifts. On higher lifts Alpine Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the control arms. The HD Forged Adjustable Front and Rear (4"+) Track Bars and Rear Track Bar Bracket improve steering response center the axles to optimize vehicle roll center and reduce body roll for unsurpassed handling. Alpine IR Control Arms feature our all-new IR (Independent Rotation) Bushings. These innovative bushings remove bushing bind during full suspension travel for less overall bushing load during articulation resulting in unrestricted droop as well as a noticeable ride improvement whether on the highway or the trail. This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems provide reduced noise vibration and harshness (NVH). Alpine RT Suspension Systems are for the Jeeper who wants it all!
